No job is ever the same. In this business it is very hard to give blind bids because of the uncertainty surrounding each job. Every concrete floor is different and every floor has a different history of treatment. That creates unique challenges when heading into a job.
We also love the customers that we work for, and Christopher Kunes Contracting has been a great customer of ours. He came to us with his latest project, a Jersey Mike’s Sub shop in York, PA. The previous use of this floor left behind a lot of mastic/glue from the tiles that used to cover the floor. When the demolition phase started, they began to remove the tiles and left behind a number of divots in the floor.
Our first job was to prepare the floor by grinding the mastic off. We used 30/40 metal bond diamonds to do that, followed by 60/80 metal bond diamonds. After the floor was ready, we began polishing with our 100 grit transitional diamonds and worked our way up to 1500 grit. In the end the job looked spectacular.
Mar-Allen Concrete was renovating the I-476 bridge ramps going down into Clark’s Summit, PA. They were ready to install a high friction overlay and needed the concrete appropriately prepared. Naturally they contacted us about shot blasting the bridge so their overlay would properly adhere and give lasting quality and reliability to the ramp.
Since the job was time sensitive our crew went up the night before and stayed in a hotel in order to start working first thing in the morning with no time lost. Deck had tines and our crew blasted to a Concrete Surface Profile (C.S.P) of 5-6. Using our diesel powered BW machines we were able to shot blast 45,000 sq. ft. in just 8 hours. As always we magnet swept and cleaned up excess shot after the job.
New Hudson Facades recently created their new manufacturing facility in Boothwyn, PA. They decided to go with polished concrete from Shot Blast Inc. for their office and break areas.
These areas see heavy foot traffic, so they require a floor that is both durable and easy to clean. Polished concrete contains no sealer, wax, or coating to wear off. Additionally, the high reflectivity of these floors reduces the need for artificial lighting makes the space look bright and clean.
As you can see in the photos below, New Hudson Facades went with a glossy slate to suit their office decor. However, we offer a wide variety of colors that you can find here.
For more reasons this flooring is ideal for offices and warehouses, see a previous blog post called Why Polished Concrete.
How do you remove 1/4 inch of tuff Epoxy/elastomeric Urethane from 350,000 square feet of parking deck on 5 different levels in a timely manner?
Case Study: Elastomeric Urethane membrane removal at the Philadelphia Parking Authority facility next to the Philadelphia Convention Center, 350,000 square feet
This was a very sensitive project in that the deck needed major restoration and concrete replacement and scheduling was very critical due to the fact that the Philadelphia Convention Center relied on this structure for most of its parking.
During the scarification process the membrane is chipped away using carbide cutters, leaving the concrete with a profile of CSP 6-9, this profile is too rough for some material manufactures so we can diamond-grind the surface to reduce the profile to the material manufacturers requirements. Next, we shot blast the surface to remove any laitance and micro fracturing caused by the scarification process. The deck is now ready for material applications.
Philadelphia parking garages see heavy traffic, so maintaining proper maintenance is necessary. The main purpose of parking deck membranes is to protect the concrete deck from water and salt intrusion, which can eat away at rebar and the supporting structure. When the deck is prepared properly and a high performance membrane system applied, it can last from 10 to 20 years.
The General contractor for this project was Melrose Construction, Inc. of North Wales, PA. When Bob DiFerdinando, Project Manager for Melrose, decided on who was going to do the surface preparation, he chose Shot Blast Inc. because of our preparation and membrane removal capabilities. No other preparation contractor had the necessary equipment and expertise to do this type of work in the time frame allotted. This project turned out to be a major success for Melrose Construction and the Philadelphia Parking Authority.
Parking garages see a lot of traffic (pun intended), so it’s important that the flooring remains in good condition. Parking decks are covered in a polymer coating that protects the surface from normal contaminants. This membrane coating needs to be removed every 10-15 years to ensure that the surface remains durable.
